8 Claims. (Cl. 84-330) ,Thepresent invention relates to a musical whistle .and

more particularly relates to a whistle for playing tunes.

It is an object of the present invention to provide a whistle of simple and inexpensive structure which may be used to play various tunes by following notes printed on a card associated withthe whistle.

Another object of the present invention is to provide a musical whistle in which there is provided a member adapted to simultaneously vary and indicate the particular notes being played. This is accomplished by providing a resonant chamber of transparent material with a piston within, which may be varied in position and aligned with notes on a card positioned behind the transparent tube.

These and other objects and advantages of the present invention will be more clearly understood when considered in connection with the accompanying drawings in which:

Figure 1 illustrates a front elevation of the invention;

Figure 2 illustrates a side elevation of the invention;

Figure 3 illustrates a cross section taken substantially along the line 3-3 of Figure 1; and

Figure 4 illustartes a cross section of a detail taken along the line 44 of Figure 3.

The whistle illustrated and described is preferably made of plastic material and may be so constructed as to be quite simple in structure and assembly. An air tube or conduit 1 is provided with a constricting wall section 2 forming the constricted passage 3 at one end of the conduit 1. This constricted passage 3 is aligned with or substantially aligned with an air deflecting edge 5 formed on the far side of a hole 4. This hole 4 is formed in the shape of a T, with the pair of opposite projecting recesses 6 illustrated in Figure 4. The air conduit 1 is positioned normal to the transparent tube member 7 which forms a resonant chamber for the whistle. This resonant chamber or tube 7 is open at either end with the lower end positioned directly above the opening 4. A piston 8 made of suitable material such as sponge rubber is slidably positioned within the resonant tube 7. A shaft member generally designated 9 projects through and is secured to this piston 8. The shaft member 9 consists essentially of an end segment 10 onto which is fitted the piston 8. Two projecting legs 11 and 12 parallel with one another extend downwardly from the segment 10 through the tube 7 and opening 4 with the legs 11 and 12 positioned respectively in the recesses 6 of the opening 4. The lower end of the legs 11 and 12 are joined together by the member 13 to form a gripping handle whereby the piston 8 may be raised and lowered by a corresponding movement of the handle 13. Aligned with the air conduit 1 is an extended section 14 generally rectangular in cross section and projecting somewhat beyond the tube 7. This projection 14, which is enclosed, is adapted to receive a card member 15, with the card member 15 having a rectangular hole at its lower end sized to fit snugly about the projec- 2,823,570 Patented Feb. 18, 1958 :sively with successive notes being indicated by connecting lines ,18. Different time values of notes are indicated by providing half notes in solid color as at 19 and whole notes in outline as at 20. The particular method of indicating different time values of notes may, of course, bevaried. The card 15, when positioned on the projection 14, may be fitted close behind the tube 7. As this tube 7 is transparent and as the piston 8 may :readily be seen through the tube, it may thereby be visibly aligned with the notes indicated on the card 15. Thus, an operator by blowing into the whistle and simultaneously .raisingand :lowering the handle 13 may 'varythe position of the piston 8 to align with the various notes 17 and thereby play the tune printed on the card 15.

In order to permit the operator to read the notes readily an extension 21 formed preferably of a flexible plastic material may be provided at the end of the air conduit 1. In this way, the notes may be positioned at a greater distance from the operators eyes, thus permitting an easier operation of the device.

If desired, the resonant tube 7 may have inscribed thereon a series of note indicating elements 22, which permit the operator to compose his own songs or to play memorized songs by merely referring to the note elements indicated on the resonant tube.

Having now described my invention, I claim:

1. A musical Whistle comprising an air conduit terminating in a constricted passage, a transparent resonant tube positioned angular to said conduit having an opening at one end, an air deflecting edge positioned at said opening and aligned with said constricted passage, a movable piston positioned within and adapted to vary the resonant frequency of said tube, said piston being visible through said tube wall, and note indicating means formed on said tube and with which said piston may selectively be aligned to obtain predetermined notes from the whistle.

2. A musical whistle comprising an air conduit terminating in a constricted passage, a transparent resonant chamber positioned angular to said conduit and having an air deflecting edge aligned with said passage, a movable piston positioned within and adapted to vary the size of said chamber, said piston being visible through said chamber wall, and note indicating means disposed adjacent the tube along the course of movement of the piston in the tube and with which said piston may selectively be aligned to obtain predetermined notes from the whistle.

3. A musical whistle comprising an air conduit terminating in a constricted passage, a transparent resonant tube mounted on and normal to said conduit and having an air deflecting edge aligned with said passage, means forming an opening between said passage and edge, a piston movably mounted in and adapted to vary the resonant frequency of said tube, said piston being visible through said tube wall, an actuator secured to said piston and extending through said opening out of the tube for permitting an operator to manually move the piston, and note indicating means formed on said tube and with which said piston may selectively be aligned to obtained predetermined notes from the whistle.

4. A musical whistle as set forth in claim 3 wherein said opening has recessed sections on either side thereof extending respectively through said recessed sections.

.. asaawo 5. In combination, a musical whistle having a transparent resonant tube and a piston movable within and adapted to-vary the :resonant size sof-said tube and a {card disposed adjacent the tube and having imprinted thereon a series of musical note representations .with

which the piston may be consecutively aligned to obtain a series of notes from the whistle; I Y

6. A musical whistle having" a transparent resonant tube, a piston movable within and visible through the tube, and'a card having note indicating means imprinted thereon and disposed along the length of the tubel, and means for selectively moving the piston adjacent the indicating means toobtain different predeterminedtones from the whistle; e 7

7. A musical whistle having a transparent resonant tube, an air conduit and whistlelsounding means normal to said'tube, a piston movable in the tube for varying the resonant length of and visible through said tube, and

a card mounted parallel to the tube and having imprinted thereon a series of note indicating means in a selected arrangement and with which the piston may be success'ively aligned to obtain a series of tones from the whistle.

8. A musical whistle comprising an air conduit terminating in a constricted passage, a transparent resonant tube mounted on and normal to said conduit and having an air deflecting edge aligned with said passage, means forming an opening between said passage and edge, a piston movably mounted in and adapted to vary the resonant frequency of said tube, said piston being visible through said tube wall, an actuator secured to said piston and extending through'said opening out of the tube for permitting an'operator to manually move the piston, a card having note indicating means imprinted thereon disposed along the length of the tube with which the piston may be consecutively aligned to obtain a series of notes from the whistle, and means for securing said card to said tube.
